Programming / PATS Security

For Plug and Play you must do the following three steps:

Step 1: Match your part number per above fitment guide

Step 2: Please check with your mechanic regarding VIN programming as it may be required.

Step 3: If your vehicle has PATS security (Most Ford/Lincoln/Mercury's do) you must have your keys programmed. We recommend you have this done by your local locksmith. In most cases they will travel to your location and the process takes less than 30 minutes. No towing necessary and your local locksmith will be cheaper than a dealer.
